New Project: High quality wallpapers?

Are there any artists, currently taking commissions, that specialize in high quality wallpapers? I have at least 3 computers, each of which with a character associated with it. These are close to what I mean:

There are certain things I'm looking for specifically though...1. Resolutions: 1920x1080, 3840x1080, 5760x1080, 1024x768 (My laptop is not widescreen), etc. Really, artists that are used to drawing in high res should already have some idea how to work the layers so they scale right in different resolutions.2. Matching: Using the exact same background with different themes would be lazy, but using a similar design in different colour schemes or different designs with a theme that ties them together would be appreciated. At least 2 of my computers sit side by side 24/7 so it'd be weird if they didn't match to some degree.3. Nothing important on the left hand side of the screen: When I get busy, my desktop gets cluttered, sometimes with icons all the way to the center of the screen. For the art to be fully visible, it should be near the right side if possible.4. No stock photos, clip art, or stealing from Google images: I shouldn't have to explain this. If I wanted to copy/paste my old commissions onto a design I looked up, I have the Photoshop experience to do it. I'm looking for an artist who can make their own design. It doesn't have to be complex, but preferably a LITTLE more effort than a gradient filter, tiled texture, or plain colour.

Just wondering who is out there and how much they charge. I still need to get better references made up for some of the characters. Post your interest, refer an artist who you know does these kinds of commissions, or PM me. ^^ Thanks.
